Deconfined pseudocriticality in a model spin-1 quantum antiferromagnet
Vikas Vijigiri, Sumiran Pujari, Nisheeta Desai
Berry phase interference arguments that underlie the theory of deconfined quantum criticality (DQC) for spin- antiferromagnets have also been invoked to allow for cont…
Ground state many-body quantum entanglement of frustrated transverse field models on square lattice
Vikas Vijigiri, K G Paulson, Saptarshi Mandal +1
We study the ground state (GS) many-body quantum entanglement of two different transverse field models on a quasi-2D square lattice relevant to a Hydrogen-bonded crystal, i.e, squa…
Dipole-dipole interaction induced phases in Hydrogen-bonded squaric acid crystal
Vikas Vijigiri, Saptarshi Mandal
We study analytically the finite-temperature phase diagram of proton ordering of a quasi-two dimensional hydrogen-bonded system, namely the squaric acid crystal($\text{H}_2\text{C}…
Classical ground states, spin-wave and PCUT analysis of system
Vikas Vijigiri, Saptarshi Mandal
We study an organic Hydrogen bonded material analytically and map out the phase diagram as well as low energy excitations in the relevant parameter space. At zeroth or…
